It has an intermediate 'stable' state, depending on from _where_ you release it. If it's released by its higher apex, it falls to the intermediate position before it falls down flat. From the bottom, it just falls over.
B. Blaze Hey, did you had in mind when you posted this that you were like - letting a print, and peoples years later could still see and answer to this comment ? that's goddamn badass.
+Tim-J.Swan I have been blocking this channel many times but youtube thinks it's funk to play with my minde so they put it back in my recomended folder over and over again.
+gimmie55 +Christopher Kim I don't see these 3 dots. Can you post a screenshot? I'd LOVE to be able to get rid of some of the recommendations I never want to click. Sometimes I click them just so they will go away.
+Tim-J.Swan it's impossible. you can pick "not interested -> i've already watched this" as many times as you want, youtube will still continue recommending videos you've already watched. the algorithm is made entirely for maximizing profits, not to make your experience better. youtube sucks.
lol its basically just a piece of metal rotating in a block of wood, like you said it doesn't hit the corners and it wouldn't pivot like that in a pliable surface, rather, it would drill a circular (or whatever shit shape) hole.
fuflang if you watch at the 3:10 mark, you can see the rounded triangular part is not the cutter, but in fact part of the mechanism.There is an extrusion coming out of the rounded triangular part that is the cutter.
+Larry Sigman The first time it fell it rolled onto its tip before falling over. Second time it fell over without rolling first. A bit pointless but there you go.
I have ask myself this every day and every night for the last nine years. I have put blood, sweat and tears into contemplating the circularity of my circle and I finally thought I had found the answer to my questions. Nope, my circle's circularity is still most definitely in question.
From someone who has shared in this very doubt, You're circle will reach maximum circularity when the radius is constant all the way around. Let that be your guide, and may you reach that ultimate level of inner peace achieved only by those who know to what degree of trigonometric perfection their circle appertains.
Back in the early 70's I used to see those shapes floating in mid air along with many colorful traces and flashes but that's another story for another time.
Totally useful for mountain/motor bike rear suspension. The linkages let the rear wheel travel in an arc, but compresses a shock which can only be compressed along a straight path.
that is the mechanism that allows the drill (that that is part of) to drill a square hole. Thats why it is sitting on a piece of wood when it shows the zoomed out bit
The reason why this video is so interesting is that it creates movement through unexpected methods. Such as the linkages shown at the end. Such complex methods (yet relatively simple) through joints in metal pieces stabilises the flawed ability for humans to draw straight lines without the need of something the pen can use a direct guide to such as a ruler. The use of simple mechanisms can be incorporated for precise medical operations, intricate production of cars and ETMs, etc.
I thought that for a long time, but then I just realized that the reuleaux rotor-esque thing isn't what's drilling the hole, and the hole they are talking about isn't the square that's already there. The square is the shape that's being drawn by the silver thing protruding from the curved thing. You can see it best from the second angle. 2:57
Love the Dudeley's dissection especially. Those hinges are fascinating with the perfect preparation of the four wooden pieces that end up as a triangle ... the next viral toy gift for "dummies." Another one reminded me of Jacob's ladder. Thanks for your careful videos.
I do love the "drilling a square hole." The bit doesn't look balanced and, if you actually put that thing on a drill that rotated at high rpms, it looks like it would be really, really unstable.
No, actually. The point isn't to drill with the edges of the shape. The bit would be on the little round thing protruding from the shape. The square it's in is just to guide it. Anything else that seems useless or wrong probably isn't, if you know what it's for. Check out the website.
there are square drill bits though. A fellow named v8hatch has a video of one made by a chinese company up on his channel and there are other videos around. Theyre amazing, and significantly more complicated than what was presented here.
You designed the most complicated ruler on the planet that could only draw a few inch long line utilizing at least 3 times as much desk space as the line you wanted to draw.
The description says this is a compilation of videos from the book of that title. I'm assuming it's an in depth text with these videos on a CD or TH-cam as clarification for some of the more complex points. Such as the objects of constant width. Who would ever believe that something other than a sphere would do that without at least a little proof? Those shapes (and the square drill bit) are based off the Reuleaux triangle, made through the intersection of three circles of the same diameter.
I can imagine the slotted elipses would have a lot of force in small areas if it was used for automobiles. And placing the axle properly seems complicated. but youre right, transportation needs to be reinvented from the ground up
When scientists first started experimenting with electricity hundreds, I would almost guarantee most people would have said something similar and seen no practical uses for electrical technology. Just because something doesn't look like it has a use now, doesn't mean it won't at some point. Modern math and science is based on its foundations, and the more we know now, however trivial it seems, the more we can do tomorrow.
I could play with all of this for hours if not days. If you see a death in the news of some kid who watched slotted Elipses all day, send a flag to my wife.
I still don't know how round my circle is.
There was no sound. Still watched this random recommended video
same
+Joshua Wheeler same
I don't see why these guys aren't super popular, I found them on iTunes, they have like no traffic. Incredible vocals, I'm tearing up a little.
I dont know what this is but I watched it
Same
Not sure what was going on with that two tip tetrahedron
roger201288 Yeah, whats that besides looking like a triangle falling over?
It has an intermediate 'stable' state, depending on from _where_ you release it. If it's released by its higher apex, it falls to the intermediate position before it falls down flat. From the bottom, it just falls over.
holy shit man how did you know?? thats fucking awesome.. now i see
'' This is a compilation of videos from my book, ''
What?
B. Blaze Hey, did you had in mind when you posted this that you were like - letting a print, and peoples years later could still see and answer to this comment ? that's goddamn badass.
Why Am i watching this right now
Solids of Constant Width is the best name ever for a Prog Rock band
Godawful prog rock
How do you tell TH-cam to un-recommend you a video? I've already seen this stuff.

How did I get here? TH-cam why?!
Those constant width solids are beautiful.
the solids of constant width blew my mind
I still don't think that thing would truly drill a square hole...
Yeah, I notice nothing touches the corners.
lol its basically just a piece of metal rotating in a block of wood, like you said it doesn't hit the corners and it wouldn't pivot like that in a pliable surface, rather, it would drill a circular (or whatever shit shape) hole.

score that cut enough and you end up with a hole, that's how drills work
Jack McWaffle a true drill has a rotating cutting tip.. this doesnt. Not to mention it wouldn't fill out the square it's outlining..
Someone explain the two-tip tetrahedron part please? All I see is a triangle falling sideways.
ikr
+Larry Sigman The first time it fell it rolled onto its tip before falling over. Second time it fell over without rolling first. A bit pointless but there you go.

How did I get to this dark corner of the internet
Chris Sangwin: "What's deinterlacing?"
+Baba Yaga Princeton university can figure out how to draw a straight line using hinges and brass rods but cant de-interlace an .avi file. Lol.
Totally useful for mountain/motor bike rear suspension. The linkages let the rear wheel travel in an arc, but compresses a shock which can only be compressed along a straight path.
Loved it. The rotation to straight-line movement things were the best.
anything will roll as long as it`s center of mass remains in a straight line while rolling
What's with the interlace? It's distracting.
that is the mechanism that allows the drill (that that is part of) to drill a square hole. Thats why it is sitting on a piece of wood when it shows the zoomed out bit
The reason why this video is so interesting is that it creates movement through unexpected methods. Such as the linkages shown at the end.

YEaahhhhh.... It's time to go to sleep.
Great video to watch when high 10\10
The two-tip tetrahedron absolutely BLEW MY MIND!
This video should be part of every discussion on interlacing.
Why am I here
+Mike Dang Nice question ...
+Mike Dang Nice i love philosophy
what does any of this have to do with anything???
+Tamara Villa Waalkens Engineering. Oscillating motion. Pretty obvious, if you ask me.
+rippspeck get roasted 🔥
The important of useless things.
I never realized just how lopsided my circle was.
Thank you.
This is just awesome. Brings me back to dynamics and calculus 3. People obviously don't appreciate the mathematics of this video.
3:20 ILLUMINATI CONFIRMED!
+StarTrek123456 Fuck off, jokes dead.
Anthony Lamanna no.
+StarTrek123456 What are you, fucking 10?
That Guy With the Pointlessly Long Username That You Are Wasting Your Time Reading Right Now no.
how incredibly unimpressive!
yes! now i can know how round any circle is!
Try painting the edges with something that leaves a trace (and roll the figures over paper) the left over patterns are quite interesting
BORRRIIIIIINNNNNGGGGGGGGGGGG...................................................
it seems like this video wasn`t made for the likes of you...
Its boring for you because you have an attention span of a 5 year old child.
INTERESTIIIIIIIIIINNNNNNGGGGGG.....................
those straight line linkages are pretty cool
I thought that for a long time, but then I just realized that the reuleaux rotor-esque thing isn't what's drilling the hole, and the hole they are talking about isn't the square that's already there. The square is the shape that's being drawn by the silver thing protruding from the curved thing. You can see it best from the second angle. 2:57
It's the little poky thing on the spinning part that moves in a perfect square.
the constant width objects are so cool!
As an engineering major, this is a cool video.
I got it now. But you would need many shaped drill holders like that for different sizes holes.
That's what I would call "a beautiful mind". Awesomeness.
Love the Dudeley's dissection especially. Those hinges are fascinating with the perfect preparation of the four wooden pieces that end up as a triangle ... the next viral toy gift for "dummies." Another one reminded me of Jacob's ladder. Thanks for your careful videos.
Years before these became popular in 3d printing circles, there was this
When the square became a triangle. MIND BLOWN
What beautiful structures!
For a question like that, the video showed a remarkable lack of circles - and a lot of elaborate ways of drawing a line.
that was magic like
there is no need to music
i think that was the real music
good job sangwinc
3:39 is how you check how round your circle is
3:59 and 4:28 is to check how straight your line is
I'm not sure what I just watched, but I enjoyed it very much!
I do love the "drilling a square hole." The bit doesn't look balanced and, if you actually put that thing on a drill that rotated at high rpms, it looks like it would be really, really unstable.
The square hole literally blew my mind
The drilling of the square hole isn't getting all the way into the corners, it would still be a mostly round hole.
Thank you for not having annoying background music
Now I get it! Wow it was right in front of me.... Thanks.
Great background song!
Lol, when i got back and re-watch it i laughed SO hard!
I'm surprised the number of corrupted comments on such an amazing display of machinery, keep it up!
This... Is so beautiful.
i loved the solids of constant width. were the people who made these geniuses?
the soundtrack had me in tears
No, actually. The point isn't to drill with the edges of the shape. The bit would be on the little round thing protruding from the shape. The square it's in is just to guide it. Anything else that seems useless or wrong probably isn't, if you know what it's for. Check out the website.
The two tip tetrahedron was definitely the best one.
It turns out, my circle is not as round as I originally thought it was.
The thing point out of it moves in a square, so it you replace that with a pencil and did in on a piece of paper it would draw a perfect squared.
they have a curvature of zero on each end, which means they can be balanced and stacked on top of one another.
We can already drill square holes, it's called a mortise.
the slotted eclipses were really trippy!
I thought that at first myself.
I think it is that it appears to form a tetrahedral shape while it falls despite only having three sides/vertices.
Before watching the video I saw your comment and my hopes was high, and was like when the hell is the music going to come in.
It's called a rattleback. Check out the wiki article. They're pretty neat little things.
why is everyone dissing this video. This is some cool stuff.
there are square drill bits though. A fellow named v8hatch has a video of one made by a chinese company up on his channel and there are other videos around. Theyre amazing, and significantly more complicated than what was presented here.
Intriguing and thought provoking mechanisms. thank you for sharing. =)
Hope you understand its about the tip( the smal round thing infront of the triangle thingy)
gotta say, the two-tip tetrahedron at 2:01 really wiped the floor with the rest of them.
best looking book i ever read
If they made a universal drill bit that made square holes... i'd buy it
This is wonderful!
this is so beautiful
At 4.08 is how AMF did make their sweeps for their pinspotters. (bowling machines)
I constantly kept checking if my sound was enabled...
Using this as a sleep-aid. Thanks
Oh, boy! That egg sure was super!
Beautiful!
You designed the most complicated ruler on the planet that could only draw a few inch long line utilizing at least 3 times as much desk space as the line you wanted to draw.
Lol when I see the title I was like "pretty freakin round!" so I clicked on it hahaha
dirty thoughts!

Yeah, Hart's A-Frame is pretty cool, but I tend to just use a straight-edge

I found out my circle is pretty round. Good shit
I decided to play Chaccaron Maccaron in the background and it's actually rather amusing.
the super egg was really cool.
I could play with all of this for hours if not days. If you see a death in the news of some kid who watched slotted Elipses all day, send a flag to my wife.
I don't see what is so special about making some reandom objects that is pure logic and then name it after yourself..
Beautiful.
